Seasons would be more drastic, because the angle of elevation of the sun would change even more from winter to summer everywhere on earth. For the northern half of Earth the Northern Hemisphere , the winter solstice occurs annually on December 21 or For the Southern Hemisphere, the winter solstice occurs on June 20 or On Friday, June 21, the sun brightens our skies longer than on any other day in This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.

The Seasons We all know that the Earth makes a complete revolution around the sun once every days, following an orbit that is elliptical in shape. The Relationship Between Length of Day and Temperature There is a lag between the longest day of the year and the warmest average temperatures for most mid and high latitude locations.
Current Weather. The amount of insolation varies depending on latitude, the time of day, the time of year, and atmospheric conditions. Think about how a beam of light from a flashlight changes depending on its angle. When the Earth is near its perihelion, it is winter in the Northern Hemisphere and summer in the Southern Hemisphere. About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface.
Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system. Balancing Act Thus, it is critical that planets have a means to lose some energy to outer space. Since Earth is surrounded by the vacuum of outer space, it cannot lose energy through conduction or convection.
